实例----------Examples----------
## function call by atomic arguments[#原子参数的函数调用]
forward.curve <- pricefutures(ttm = 0.2 * 1:10, s0 = 10, delta0 = 0,
alpha = 0, lambda = 0.02, r = 0)
plot(forward.curve, type = "b")
## function call via schwartz2f-object. [#函数调用通过schwartz2f对象。]
obj <- schwartz2f(delta0 = 0, sigmaE = 1e-5) # Make convenience yield inactive[便利收益不]
forward.curve <- pricefutures(ttm = 0.2 * 1:10, s0 = obj, r = 0, alphaT = 0)
plot(forward.curve, type = "b")
